Electron beam focusing electrode and electron gun using the same
摘要:
An electron beam focusing electrode and an electron gun using the same may include a plate having a polygonal through-hole; at least a projecting portion formed on at least one side of the through-hole. By using the electron beam focusing electrode, a spreading phenomenon of an electron beam having a rectangular cross section may be reduced. Further, the output of the electron gun may be increased, and electron beams may be easily focused.
